Rainbow Papers Limited located at Survey No. 1453, Village: Rajpur, Taluka: Kadi, Dist.: Mehsana in Gujarat state, is an existing unit, engage in manufacturing of Kraft Paper, Duplex paper, poster paper and News Print paper-14000 TPM and having Captive power generation facilities with rated capacity of 15 MW. Now, management is envisaging increasing Power generation capacity to 50 MW by adding 35 MW in two phases (20 MW power generation in Phase-1 & 15 MW power generation in Phase-2) to fulfill the present market demands on same process route. The management is engaged in manufacturing activities since last long time and has a wide experience in the similar field. 1.2 Purpose & Need of E.I.A Environmental Impact Assessment (E.I.A) is a formal document provided by the project proponent and preferably prepared by an independent consultant, which summarizes the process and results of the environmental analysis of a project having the potential for significant and diverse impacts. Environmental analysis is the process of evaluating the environmental impact of a project and identifying ways to improve the project environmentally by preventing, minimizing, mitigating and or compensating for adverse impacts. M/s. Rainbow Papers Limited falls under the category of 1(d) of schedule of EIA Notification, 2006 “Thermal Power Plants” and categorized under “B”. Therefore, units require Environmental Clearance of the proposed expansion project. REIA Study for Captive Power plant of Rainbow Papers Limited 1-1 San Envirotech Pvt. Ltd. - Ahmedabad In view of the above monitoring work has been carried out for all the environmental attributers by M/s. San Envirotech Pvt. LtdAhmedabad. The Environmental (Protection) Act-1986 (Environmental Impact Assessment Notification, 2006) established the requirements for preparing Environmental Impact Assessment (E.I.A) in India. The EIAs subsequently have been prepared, on an individual basis for each new/development project. While the project specific EIAs have been successful to varying extent in the incorporation of environmental objectives in the project design, several experiments have been done to address the issue of cumulative environmental impacts by carrying out Regional Environmental Impact studies. This has given a basis for evaluating total environmental impacts of the region and hence helped in planning at the regional level. Other uses of EIA tool have been in the Strategic Environmental Assessment (SEA), now mandatory in many industrialized countries, to evaluate environmental impacts of policies and programs. Hence, EIA tool has been improvised and used innovatively for assisting decision-makers in assessment of environmental impacts and considering alternative mitigation measures in a variety of situations. Environmental Impact Assessment (EIA) is required to be carried out only for certain categories of projects and the criteria for screening have been provided in the Act. Thus, EIA is essentially made applicable to industrial and developmental projects, which are more likely to have significant environmental impacts. Different criteria have been used for screening. Indian regulation utilizes project category based on the Scale of Impact, Sensitivity of Impact and Nature of locations as the primary criteria for deciding on the requirement of EIA for approval.

Production detail is given hereunder, Sr. No. Description Existing 1 Captive Power 15 MW Additional After expansion Phase-1 Phase-2 20 MW 15 MW Total 50 MW Generation 2.9 PROCESS DESCRIPTION The captive power Co-generation power plant will consist of the following plant/equipment. • High pressure Boiler of latest technology. • Turbo – Generator (TG) Sets: Turbine Generator with auxiliaries. • Pressure Reducing and De superheating Station • Coal handling and supply system. • Condenser along with condensate extraction pumps, piping & valves. • Compressed Air System for instrumentation and utilities. • Ash handling system • Pollution control equipment • Chimney • Electrical and Electrical Distribution System. • Instrumentation and control system (DCS) for Boilers and Turbine. REIA Study for Captive Power plant of Rainbow Papers Limited 2-6 San Envirotech Pvt. Ltd.-Ahmedabad • Cooling tower and cooling water pumps for lube oil cooler and other Auxiliaries. • D.M. plant for boiler feed water. A thermal power plant is an energy conversion center that converts the heat of coal to electricity, designed on a large scale for continuous operation. The feed water used in the steam boiler is a means of transferring heat energy from the burning coal fuel to the mechanical energy of the spinning steam turbine. The total feed water consists of re-circulated condensed steam, referred to as condensate, from the steam turbines plus purified makeup water. Because the metallic materials it contacts are subject to corrosion at high temperatures and pressures, the makeup water is highly purified before use in D. M. Water plant. The boiler has a rectangular furnace. Its walls are made of a web of high pressure steel tubes. Coal is prepared for use in boiler by crushing the rough coal to pieces less than 6 mm in size. Prepared coal is air-blown into the furnace from fuel nozzles and it is combusted in such a manner that maximum combustion efficiency can be achieved. This heats the water that circulates through the boiler tubes. The water circulation rate in the boiler is three to four times the throughput and is typically driven by pumps. As the water in the boiler circulates it absorbs heat and changes into steam. It is separated from the water inside a drum at the top of the furnace. The saturated steam is introduced into superheat pendant tubes that hang in the hottest part of the combustion gasses as they exit the furnace. Here the steam is superheated to required temperature to prepare it for the turbine. The turbine generator consists of a steam turbine, Gear Box, Generator, Condenser, Steam ejectors, Condensate extraction system, to generate the required power. REIA Study for Captive Power plant of Rainbow Papers Limited 2-7 San Envirotech Pvt. Ltd.-Ahmedabad The generator contains a stationary stator and a spinning rotor, having magnetic properties produce electricity when it is rotated by Turbine. The electricity thus produced is used to run the various equipments. The required steam for process is being drawn from turbine at required pressure and the balance exhaust steam from the low pressure turbine enters condenser-tube bundles that have cooling water circulating through them. Typically the cooling water causes the steam to condense. From the bottom of the condenser, powerful pumps recycle the condensed steam (water) back to the feed water heaters for reuse. The heat absorbed by the circulating cooling water in the condenser tubes must also be removed to maintain the ability of the water to cool as it circulates. This is done by pumping the warm water from the condenser through either natural draft, forced draft or induced draft cooling towers that reduce the temperature of the water, by evaporation. As the combustion flue gas exits the boiler it is routed through a rotating flat basket of metal mesh which picks up heat and returns it to incoming fresh air as the basket rotates, This is called the air pre-heater. The gas exiting the boiler is laden with fly ash, which are tiny spherical ash particles. The fly ash is removed by electrostatic precipitators to achieve exhaust gas quality as required by the statute. 2.10 INPUT REQUIREMENTS 2.10.1 Existing Operation Water Water for the existing operation is provided by own bore well.

The main sources of water pollution are from utilities with raw water treatments. RO rejects/DM rejects & boiler blow down will be a main source of effluent. The effluent will be neutralized by adding either acid or alkali to obtain required pH concentration in the neutralizing pit and it will be utilized for the paper making in the paper plant. Thus, the unit will achieve Zero Discharge. Steam Generator’s blow down The temperature of the blow down water would be in range of 100°C. The blow down will be quenched with service water and utilize for paper making in paper unit. 2.18.2 Air Pollution Control Measures As discussed previously, the main source of air pollution will be flue gas emission. The flue gas emission will be emitted through the stacks attach to boiler. Adequate height of 85 m with ladder and sampling point will be provided as per the GPCB guidelines. Chimney heights will be preferred such that the generated pollutants disperse effectively and ensure that the ground level concentrations of pollutants in the surrounding environment remain well within the permissible limits. ESP, an air pollution control measure will be provided at boiler outlet for extracting the dust pollutant from flue gas for achieving the dust concentration at the outlet of chimney as low as 150 mg/Nm3. REIA Study for Captive Power plant of Rainbow Papers Limited 2-18 San Envirotech Pvt. Ltd.-Ahmedabad The details of flue gas stacks are given in Table No. 2.8. 2.18.3 Solid/Hazardous Waste Management The entire quantity of solid/hazardous waste will be handled and disposed as per (Management, Handling and Trans boundary Movement) Rules’2008. After expansion the source of hazardous waste generation from plant will be discarded containers & used lubricating oil. Power plant ash will also be the main solid waste in proposed expansion and will be collected, packed in bags and finally utilized in house brick manufacturing plant. The used oil will be stored in closed containers, at designated place with complete flooring and proper roofing. Discarded containers will be reused/ sold to approve vendors and used oil will be sold to CPCB approved recyclers or will be used as lubricant in machines. 2.18.4 Flue Gas Emissions Combustion of fuel gases will generate the air pollutants in the form of Oxides of Nitrogen, Oxides of Sulphur and Suspended Particulate Matter. Emission of SPM Suspended particulate matters are likely to be generated from boiler of power plant. According to EPA Act, 1986 limit of SPM emission should be within 150 mg/Nm3 for thermal power plant. To obtain the desired prescribed limit of SPM, ESP of required efficiency will be installed.

Ltd - Ahmedabad Chapter 3 Baseline Environmental Status 3.1 Prelude Any developmental activities related to industrial sector are expected to cause impacts on environmental quality in surrounding area of the respective project locations. However, the intensity of environmental impacts from a specific project depends on several factors such as type of process (Physical, Chemical, fuel combustion etc.) involved in the project, processing capacity (scale/size of the project), type and extent of pollution control measures, project location, surrounding geomorphology demography, quality of life, etc. To assess environmental impacts from proposed project at a specific location, it is essential to monitor the environmental quality prevailing in the surrounding area prior to implementation of the proposed project. The environmental status within the impact zone could be used for identification of significant environmental issues to be addressed in the impact assessment study. The impacts from an industrial project on its surrounding environment are mainly regulated by the nature of pollutants, their quantities discharged to the environment, existing environmental quality, assimilative capacity of the surrounding environment and topography and terrain of the project site (its location) as well as the surrounding area. In order to identify and establish the extent of likely impacts, it is essential to gather information on existing environmental quality with regard to various components of the environment. REIA Study for Captive Power plant of Rainbow Papers Limited 3-1 San Envirotech Pvt. Ltd - Ahmedabad 3.2 Air Environment The impact on air environment would depend and has been identified on the basis of identification of sources of air pollution from various process operations; the nature of pollutants and their quantities likely to be discharged to the atmosphere; and the baseline data on air quality. The baseline data on air quality and micrometeorological conditions of the area surrounding the project site have been generated through an appropriately designed network for monitoring of Ambient Air Quality (NAAQ) within the zone of likely impacts. 3.2.1 Design of Network for Ambient Air Quality Monitoring Stations The following criteria were taken into account while designing the ambient air quality-monitoring network: Topography / Terrain of the study area Populated areas within the region Prediction of maximum concentrations and distances of their likely occurrence under prevailing meteorological conditions Representation of regional background Representation of valid cross sectional distribution in downwind direction 3.2.2 Reconnaissance Reconnaissance survey was undertaken to establish the baseline status of air environment in the study region. The prime objective of the NAAQ survey, within 10 km radial study area around the plant was to establish the existing ambient air quality levels. Six Ambient Air Quality Monitoring (AAQM) stations were selected based on the criteria used for designing the network. The locations (relative directions and distances) of these stations with respect to project site are given in Figure 3.6 and details of these stations are described in Table 3.1. REIA Study for Captive Power plant of Rainbow Papers Limited 3-2 San Envirotech Pvt. Ltd - Ahmedabad The Particulate Matter (PM10), Particulate Matter (PM2.5), Sulphur Dioxide (SO2) and Oxides of Nitrogen (NOx) were identified as significant parameters for ambient air quality monitoring, particularly because these are likely to be emitted from the industries and for which ambient air quality standards are prescribed. The micrometeorological data on wind speed, wind direction, temperature and relative humidity were collected through a weather monitoring station for the study period. The baseline status of air quality was monitored within the study area i.e. 10 Km radial distance from project site as per the latest regulatory guidelines. 3.2.3 Micrometeorology of the Area The micrometeorological conditions at the project site will regulate the transport and diffusion of air pollutants released into the atmosphere. The principle meteorological variables are horizontal convective transport (average wind speed and direction), vertical convective transport (atmospheric stability, mixing height) and topography of the area. The data on surface meteorological parameters (hourly average wind speed and direction) in the study area were collected in the month of January-11 to March-11 using portable weather monitoring station placed at the industry. The sensors of this equipment were kept at about 10 m above ground level with free exposure to the atmosphere all through the study period in winter season. In addition, data on temperature as well relative humidity were also recorded simultaneously using a data logger. Wind Rose The 24 hourly wind rose was prepared using the data on wind direction and speed collected for winter season in the study area. The same, as depicted in Figure 3.7, shows the predominant wind directions are N, NE, NNE, NNW & ENE implying that winds come REIA Study for Captive Power plant of Rainbow Papers Limited 3-3 San Envirotech Pvt. Ltd - Ahmedabad from these directions for most of the time during the period. The wind speed class 1-5 kmph occurred for 33.0 % and 6-10 kmph is 17.7 %, 11-15 kmph is 10.8 %, 16-20 is 3.2 % and more than 20 kmph is observed around 0.0 % of the time during study period. The calm condition (below 1 kmph) observed is 35.3 % of the time. The local prevailing wind pattern during the study period is in conformity with the climatologically normal of the region. The average wind speed recorded is 4.2 kmph during the study period (Jan-11 to March-11). Temperature During the study period the maximum and minimum temperatures recorded at project site were recorded as 32.50C and 9.80C respectively. Relative Humidity At project site during study period, the maximum relative humidity was recorded as 69.5% and minimum as 10.2%. Rainfall For the study, period rainfall observed nil. Seismisity: The area falls under III seismic zone and of intensity VII, which indicates it, is moderately earthquake prone zone. REIA Study for Captive Power plant of Rainbow Papers Limited 3-4 San Envirotech Pvt. Ltd - Ahmedabad 3.2.4 Ambient Air Quality Survey The ambient air quality monitoring was carried out at 6 AAQM locations, with a frequency of twice a week continuously for three months i.e. January-11 to March-11, to assess the existing sub-regional air quality status in winter season. The Respirable Dust Sampler and Fine Particulate Sampler along with the analytical methods prescribed by CPCB were used for carrying out air quality monitoring. At all these sampling locations; PM10, PM2.5, SO2, and NOx were monitored on 24-hourly basis to enable the comparison with ambient air quality standards prescribed by the Central Pollution Control Board. The data on concentrations of various pollutants were processed for different deviation, statistical minimum parameters and like maximum arithmetic mean, concentration and standard various percentile values. 3.2.5 Baseline Status The existing baseline levels with respect to PM10, PM2.5, SO2, and NOx are presented in Tables 3.2 to 3.6 with interpretation of statistical analysis of observed ambient air quality data for six locations. Presented results, represent the cross sectional distribution of baseline air quality status of the study region. Respirable Suspended Particulate Matter (PM10) An average and 98th percentile value of 24-hourly PM10 values at all the locations ranged between 57-67 μg/m3 and 63-77 μg/m3 whereas the stipulated standards of CPCB for industrial areas 100 μg/m3. Particulate Matter (PM2.5) An average and 98th percentile value of 24-hourly concentrations of PM2.5 value at all the locations ranged between 38-43 μg/m3 and 4349 μg/m3 respectively. The stipulated standard of PM2.5 for industrial area is 60 μg/m3. REIA Study for Captive Power plant of Rainbow Papers Limited 3-5 San Envirotech Pvt. Ltd - Ahmedabad Sulphur Dioxide (SO2) An average and 98th percentile value of 24-hourly SO2 value of arithmetic mean at all the locations ranged between 15-21 μg/m3 and 17-24 μg/m3 respectively, which are well within the stipulated standards of 80 μg/m3 for industrial areas. Oxides of Nitrogen (NOx) An average and 98th percentile value of 24 hourly NOx value of arithmetic mean at all the locations ranged between 15-23 μg/m3 and 17-27 μg/m3 respectively, which are much lower than the standards stipulated by CPCB for industrial areas (i.e. 80 μg/m3). 3.2.6 Identification of Impacts The identification of impacts with regard to air environment involves a careful consideration of all the major process operations, burning of fuel required for generating the energy in terms of steam and/or electricity and other activities that may lead to generation and discharge of air pollutants to the atmosphere. The main source of air pollution will be flue gas emission. The flue gas emission will be from the boilers where Coal/Lignite will be used. However, adequate air pollution control measures will provide to meet gaseous emission norms recognized by GPCB. 3.3 Water Environment Water Environment of an area is broadly classified into following categories 1. Surface waters: Rivers, drains, canal, ponds etc. 2. Ground water: Accumulation in deeper strata of ground The only source of recharging for both surface and groundwater source is from precipitation (rainfall).

Other Parameters: Potassium (ranges from 46 mg/l to 69 mg/l), Sodium (ranges from 257 mg/l to 321 mg/l), and Chloride (ranges from 247 mg/l to 459 mg/l). Conclusions: Ground water samples from villages meet the permissible limit set by the authority (BIS). Indian standard specification for drinking water is given in Table 3.9. 3.4 Noise Environment 3.4.1 Introduction Noise can be defined as an unwanted sound. It interferes with speech and hearing and is intense enough to damage hearing or is otherwise annoying. The definition of noise as unwanted sound implies that it has an adverse effect on human beings and their environment. Noise can also disturb natural wildlife and ecological system. Sound is mechanical energy from a vibrating surface, transmitted by cyclic series of compression and rarefaction of molecules of the materials through which it passes. Sound can be transmitted through REIA Study for Captive Power plant of Rainbow Papers Limited 3-8 San Envirotech Pvt. Ltd - Ahmedabad gases, liquids and solids. The number of compressions and refractions of the air molecules in the unit of time is described as its frequency. Frequency is expressed in hertz (Hz), which is the same as the number of cycles per second. 3.4.2 Methodology To understand the noise environment in the study area, a survey was conducted using Sound Level Meter at each of the eight locations, is shown in Figure 3.9. 3.4.3 Day-Time and Night-Time Noise Levels Noise survey was carried out once at each of the eight locations in the day-and nighttime during the study period. Table 3.10 depicts Lday, Lnight, Lday-night noise levels for all locations. 3.4.4 Ambient Air Quality Standards in Respect of Noise Ministry of Environment and Forest has notified the ambient standards in respect of noise in Gazette of India dated 14 February, 2000. Table 3.11 depicts these standards in respect of noise. 3.4.5 Ambient Noise Levels in the Study Area The Leq values of noise levels during daytime (Ld) varied between 55.7 to 63.8 dB (A). Highest Ld value was recorded at Bus stop Laxmanpura (63.8 dB (A)). While the Leq values of noise levels during night time (Ln) varied between 46.3 to 52.6 dB (A). Highest Ln value was again recorded at Primary School Rajapur (52.6 dB (A)). 3.4.6 Conclusions The hourly Leq noise levels recorded at various locations in the study area show considerable fluctuations because of changes in traffic movement, commercial and domestic activities in the study area. Generally noise levels in public places like hospital, temples and Bus stop have higher values in day time as per Residential area limit of 55 dB (A) but it is less than Commercial area limit of 65 dB (A). REIA Study for Captive Power plant of Rainbow Papers Limited 3-9 San Envirotech Pvt. Ltd - Ahmedabad Ambient standards both for Ld and Ln with respect to noise applicable for residential area during day-time {55 dB (A)} and night-time {45 dB (A)} are not always met at all locations. 3.5 Soil Environment 3.5.1 Introduction Soils may be defined as a thin layer of earth’s crust that serves as a natural medium for the growth of plants. It is the unconsolidated mineral matter that has been subjected to and influenced by genetic and environmental factors. Soils serve as a reservoir of nutrients for plants and crops and provide mechanical anchorage and favorable tilth. The study area has alluvial sandy loam soil locally known as Goradu (or Gorat) or Bhatta. Goradu are nothing but alluvial soils of older origin while Bhatta soils are of recent origin deposited chiefly along the banks of river. The soils of this group are moderately deep, well drained, calcareous fine soils on very gently sloping alluvial plain with slight erosion and moderate salinity; associated with deep, moderate well drained, calcareous, fine soils with moderate erosion. The study area has alluvial sandy loam soil with the following physical and chemical characteristics. 3.5.2 Soil Characteristics Samples of soils were done at 5 locations (Industry, Village Irana, Jhulasan, Dhanot, Ghumasan) during the study period and these locations are shown in Figure 3.10. The values of important physical and chemical parameters of these soil samples are depicted in Table 3.12.

Ltd - Ahmedabad Chapter 4 Anticipated Environmental Impacts & Mitigation Measures 4.1 GENERAL Predicting the net contribution on overall qualitative environmental indicators require environmental impact assessment study for the proposed units. Prediction of impacts is an important component in environmental impact assessment process. Several techniques and methodologies are in vogue for predicting the impacts due to existing and proposed industrial development on physical, chemical, biological and socio-economic components of environment. Such predictions delineate contribution in existing baseline condition for the proposed project. The additional impacts due to proposed activities are analyzed keeping in mind the baseline status. This helps assess the assimilative capacity of the environment and in turn the gravity of the impacts. Depending on the nature of the impact, suitable management plans are devised. As such it becomes important to estimate the peak incremental concentrations of gaseous pollutants caused due to the emissions from the proposed expansion of captive power plant of Rainbow Papers. Chapter 2 of this report discusses the pollution sources from the proposed plant. Mathematical models are the best tools to quantitatively describe the cause-effect relationship between source of pollution and different components of environment. 4.2 IMPACT DURING CONSTRUCTION AND OPERATION PHASE The impact assessment has been addressed for the following attributes, which may get affected due to the proposed activities of the project. REIA Study for Captive Power plant of Rainbow Papers Limited 4-1 San Envirotech Pvt. Ltd - Ahmedabad 4.3 • Impact on Topography • Impact on Air Environment • Impact on Water Environment • Impact on Noise • Impact due to solid waste generation • Impact on terrestrial ecology • Impact on aquatic ecology IMPACT ON TOPOGRAPHY The project activities include excavation of soil in the plant area and construction of the plant and storage facilities. The area of the plant is flat. Very minor or no Leveling would be required for the construction for the proposed expansion of captive power plant. No tree plantation affected because expansion will be in established plan area. During the construction, excavated soil will be restored to its original shape. Thus the impact during the construction is reversible, for short terms and insignificant. During the operation phase of the project, no impact is envisaged on the topography. 4.4 AIR ENVIRONMENT 4.4.1 CONSTRUCTION PHASE The source of air emission during the construction will include dust from site cleaning and construction activity and dust from excavation of the plant area. These emissions are expected to result in change in baseline air quality, primarily in the working area only. Dust and other emissions are not likely to spread in wider area, which would affect homes and other properties. Dust will generate within working areas and measures will need to taken to protect workers. To mitigate the impact due to Suspended Particulate Matter (SPM), regular sprinkling of the water will be done along with the construction activities. REIA Study for Captive Power plant of Rainbow Papers Limited 4-2 San Envirotech Pvt. Ltd - Ahmedabad 4.4.2 OPERATIONAL PHASE In the present study, the mathematical model that has been used for predictions on air quality includes steady state Gaussian Plume Dispersion model designed for multiple point sources. The impacts on air quality from any project depend on various factors like design capacity, configuration, process technology, raw material, fuel to be used, air pollution control measures, operation and maintenance. Apart from the above, other activities associated with any project, viz., transportation of raw materials and finished products, storage facilities and material handling within the plant premises may also contribute to air pollution. 4.4.3 SOURCES OF AIR POLLUTION The fuel consumption details are given in Table 4.1. In the proposed captive power plant, point sources emitting gaseous pollutants include the stacks from Boilers of captive power plant. Height of stacks will be 85 meters. The stack height is considered from ground level. The major air pollutants, identified from this industry, are SPM, SO2 and NOx. 4.4.4 EMISSIONS In the operational Lignite/Coal is being used in the boilers. Ratio of Fuel of Coal to Lignite will be (40:60). Similar types of stacks were monitored to get the information about emission characteristics including the emission rates of SPM, SO2 and NOx. The emission rates of SPM, SO2 and NOx & stack details for the CPP are presented in Table 4.2. Where as Table 4.3 show GPCB Stack emission standards details for Industry. 4.4.5 DISPERSION MODELLING PROPOSED PLANT OF EMISSIONS FROM THE The objective of dispersion modeling is to predict the ground level concentration during the operation of proposed plant and its impact on ambient air quality of the area. The ground level concentrations of REIA Study for Captive Power plant of Rainbow Papers Limited 4-3 San Envirotech Pvt. Ltd - Ahmedabad pollutants have been computed using computer simulation model Industrial Source Complex Short Term (ISCST-3) of United State Environmental Protection Agency (USEPA) and considering guidelines stipulated by CPCB for air pollution dispersion modeling. The key emissions from the proposed plant will be emissions of, suspended particulate matter (SPM), Sulphur dioxide (SO2) and nitrogen oxide (NOx). 4.4.6 METHODOLOGY Prediction of GLC values are made by using Industrial Source Complex Short Term Model Version–3 (ISCST-3) software approved by U.S. Environmental Protection Agency (USEPA). This model uses a steady state, sector-averaged Gaussian plume equation for application in complex terrain (i.e. terrain stack or release height) and is run using stability classes developed by Pasquill and Gifford. Following are the assumptions made while using the model: - No dry and wet depletion of pollutants - Receptors are on flat terrain with no flag pole Data Used for Computation Stack emissions data have been used for prediction of short-term incremental GLC values of SPM, SO2, NOx, using the one season meteorological data collected at site during January-11 to March-11. Details of the data used for computations are given below: Source Characteristics/Release Characteristics The details of estimated stack emissions load are given in Table 4.2. Meteorological Parameters Hourly meteorological data collected at site for the period of January11 to March-11 have been used for computing the meteorological parameters. REIA Study for Captive Power plant of Rainbow Papers Limited 4-4 San Envirotech Pvt. Ltd - Ahmedabad Dispersion Modeling Results The 24 hourly average ground level concentration (GLC) values from proposed expansion have been computed for SPM, SO2 and NOx, considering topographical features around the proposed plant and applicable stability classes. The maximum 24 hourly average GLC values for SPM, SO2 and NOx, from proposed plant are given in Table 4.4 to Table 4.6. Corresponding isopleths plotted are shown in Figure 4.1 to Figure 4.3 for SPM, SO2 and NOx. It may be noted from the computed results presented in Table 4.4 that highest 24–hourly incremental GLC value for SPM, SO2 & NOx are 3.245 µg/m3, 2.636 µg/m3 and 0.608 µg/m3 respectively is occurred at a distance of 1.414 km in North-East direction. For stable stability conditions (night time), the plume rise will be very high and dispersion will be very poor and plume will not touch ground level even at extremely large distance. At any wind velocity, the concentration peak shifts from short distance for extremely unstable stability condition to longer distance for neutral stability condition, increase in average wind velocity results in the shifting of concentration peaks towards lower distances for any specified atmospheric stability condition due to decrease in plume rise. Since the predicted 24 –hourly incremental GLC values are at full load operation added together with the background levels of SPM, SO2 and NOx remain well below the 24 –hourly ambient air quality standards for SO2 & NOx (80 μg/m3) and PM10 (100 μg/m3), the operation of proposed plant is not likely to cause any significant impact on the ambient air quality of the study area. 4.5 WATER ENVIRONMENT Impact on water environment due to the proposed expansion of captive power plant project will be, 1. Due to demand for raw water These are discussed below: REIA Study for Captive Power plant of Rainbow Papers Limited 4-5 San Envirotech Pvt. Ltd - Ahmedabad 4.5.1 Water Demand Construction phase During the construction activities required quantity of water will be drawn from existing bore well. The quantity of water is very small quantity hence there will be no significant impact on the ground water. No disposal of construction waste outside the plant and no leaching are anticipated. Operational Phase Water shall be required during operation of the captive power plant for following purposes: Domestic use Process water Cooling/Chilling Boiler Green belt Raw water requirement for, proposed expansion of Rainbow paper will be met from surface water to be provided by Sardar Sarovar Narmada Nigam Limited. However efforts have to be made to conserve water as much as possible. Also Chapter 5 proposes some additional mitigation measures to minimise the raw water consumption. In view of these factors the impact on water environment due to water use is assessed to be insignificant. 4.5.2 Wastewater Generation & utilization Rainbow paper will be utilized all the generated wastewater from utilities of power plant to paper making activities. The unit is paper producing unit from waste paper and concept of 100% recycling of waste water is adopted by the unit as per the cleaner technology and CPCB guideline for paper industries. However to improve the quality of water for recycling of wastewater generated from paper production, unit has put up a primary and secondary treatment plant. Presently unit REIA Study for Captive Power plant of Rainbow Papers Limited is reusing 4-6 San Envirotech Pvt. Ltd - Ahmedabad untreated/primary treated/secondary treated as per the quality requirement at different stage of paper process. 4.5.3 Impact on Water Environment The water environment consists of surface and ground water resources. The study area has no surface water body. Proposed Rainbow papers plant effluents will be treated in two stages. Entire quantity of effluent is recycling in process. Hence insignificant impact on water body. 4.5.4 Impact on Ground water The water required during the operation phase is made available from groundwater. The ground water requirement will be met by an existing bore well of industry. The industry has proposed recharge rainwater during the rainy season. The details are prescribed in Chapter-5 of Environmental Management Plan. 4.6 NOISE LEVEL IMPACT 4.6.1 Construction Phase The noise produced during construction may have significant impact on the existing ambient noise levels. The major work will be carried out during the daytime. The construction equipment may generate high noise, which can affect the personnel operating the machines. Use of proper personal protective equipments will mitigate any adverse impact of noise generated by such equipment. The noise level in the working environment is compared with standards prescribed by ISO 3746. The acceptable limit for each shift being of 8-hour duration, the equivalent noise level exposure during the shift is 90 dB(A). Hence noise generation due to excavation may affect workers, if equivalent 8 hours exposure is more then the safety limit. The noise level likely to be generated during excavation, loading, transportation of construction materials will be in the range of 70-90 dB(A) and this will occur only when operate together and simultaneously. This all the equipment will REIA Study for Captive Power plant of Rainbow Papers Limited be a remote 4-7 San Envirotech Pvt. Ltd - Ahmedabad possibility. The worker in general are likely to be exposed to an equipment noise level of 80-90 dB(A) in an 8 hour shift for which all statutory precautions as per lows will be taken into consideration. 4.6.2 Operational Phase The main sources of noise within the plants are: Steam turbine, boiler, Air compressors and transferring pumps. Suitable noise control system will be provided to ensure that noise at the ventilation openings does not exceed 90 dB (A) at 1 m distance in conformity with ISO 3746. The noise level shall, however, exceed the above limits for a short period during start-up of power plant. To reduce the impact of noise from power plant, earplugs will be provided to the workers. The continuous source of noise during plant operation will be boilers, transferring pumps and string equipment of reactors. The other sources of noise are the movement of vehicles along the road. The typical industrial noise sources are given in Table 4.7 and details of damage risk criteria for hearing loss on the basis of OSHA are given in Table 4.8. The results of monitoring carried out in the region have been presented in Chapter 3. The permissible levels in the ambient environment are presented in Chapter 3. The results are below the standards prescribed for Industrial environment. It can be concluded that the impact on noise environment will be long term but insignificant. The noise standards specified by regulations shall be met. The mitigation measures being followed/proposed for minimising impacts on noise quality are provided in chapter 5. 4.7 SOLID WASTE MANAGEMENT The disposal of solid waste that will be generated in the process and ETP is mainly Fibers which are reuse in next cycle of process. Biological sludge which ever will be use as manure in green belt in plant premises. Other waste like Heavy foreign material, Saleable Plastic & Straps etc which is sale to recycles. REIA Study for Captive Power plant of Rainbow Papers Limited 4-8 San Envirotech Pvt. Ltd - Ahmedabad 4.8 SOCIO-ECONOMIC IMPACTS: CONSTRUCTION & OPERATIONAL PHASE The construction will be within the existing plant premises. Land is already in possession. Therefore no displacement of person is envisaged. The plant is requiring educated and trained manpower & unskilled manpower. The surrounding area has got good educational facilities at Ahmedabad. However, some persons with requisite experience may come from outside also, but most of them may stay at Ahmedabad. The operation of the proposed plant requires a workforce of 200-250 persons. Some immigration may takes place but the same will be so small that its impact on demography of the area will be insignificant. In view of the above the overall impacts on socio-economic environment due to the proposed plant are long term and positive in nature. 4.9 ECOLOGICAL IMPACTS 4.9.1 Effect on Plants The area around Rainbow plant has a dense growth of vegetation around it. Various trees, shrubs and herbs are found around it, a list of which is given in Chapter 3. None of the plants are in the list of Endangered Plant Species. The high Stomatal Index of Azadirachta indica, makes them susceptible to SO2. However, the SO2 emissions from the industry will be well within limits. Hence, no major adverse impact is expected on these plants with the increased emissions. NOx is less damaging to plants. Vegetation injury such as marginal necrosis is anticipated only in localized regions immediately adjacent to excessive industrial sources. In the proposed context, the levels of NOx emission are not very high. REIA Study for Captive Power plant of Rainbow Papers Limited 4-9 San Envirotech Pvt. Ltd - Ahmedabad The high SPM levels may harm leaves by blocking stomata and thus interfering with exchange of gases during photosynthesis and respiration and also cause abrasion of plant surfaces when the wind blows. But the site is not subjected to high-speed winds and the plants can be expected to be free from any major impacts of SPM on plants.

Ltd - Ahmedabad Chapter-5 Environment Management Plan 5.1 INTRODUCTION Assessment of environmental and social impacts arising due to implementation of the proposed project activities is at the technical heart of EIA process. An equally essential element of this process is to develop measures to eliminate, offset, or reduce impacts to acceptable levels during implementation and operation of projects. The integration of such measures into project implementation and operation is supported by clearly defining the environmental requirements within an Environmental Management Plan (EMP). Normally, potential impacts are identified early during the initiation of project, and measures to avoid or minimize impacts are incorporated into the alternatives being considered. In this respect, some of the most important measures to protect the environment and local communities become integral to the project design, and may not be reflected in a formal EMP. Rainbow by way of EIA study propose to identify all the likely potential impacts, collect data information and incorporate all the measures necessary to avoid or minimize impacts on surrounding environment. Many of the mitigation measures are in place. It is desirable to collect even such information in the EMP to facilitate better assessment and communication as well as improve the systems and technologies to improve mitigation for environmental components having moderate residual impacts. REIA Study for Captive Power plant of Rainbow Papers Limited 5-1 San Envirotech Pvt. Ltd - Ahmedabad 5.2 OBJECTIVES OF ENVIRONMENTAL MANAGEMENT PLAN The objective of the Environmental Management Plant is summarized hereunder, Prevention: Measures aimed at impeding the occurrence of negative environmental impacts and/or preventing such an occurrence having harmful environmental impacts. Preservation: Preventing any future actions that might adversely affect an environmental resource or attribute.

Rainbow Papers Ltd. Captive power plant will be carried out in the existing premises, construction activities will be required only for the installation of new plant and machineries. Hence, there will be some adverse impacts on the quality of air and water but, this will not cause adverse effects on the surrounding atmosphere. No disposal of construction waste outside the plant and no leaching are anticipated. The impact will be temporary and negligible. The construction activities for installation REIA Study for Captive Power plant of Rainbow Papers Limited 5-3 San Envirotech Pvt. Ltd - Ahmedabad work shall generate noise and dust within working areas. Therefore, measures will be taken to protect workers. In order to mitigate the adverse environment impacts during the construction phase, regular sprinkling of the water will be done. Construction phase results in temporary environmental pollution except for the permanent change in local land use pattern and aesthetics, in certain cases. Such pollution is mainly due to site preparation, civil works, transportation, storage & handling of different kinds of materials including inflammable/hazardous materials, construction workers’ sanitation etc. These are usually short-term impacts as compared to those during operational phase. 5.5 ENVIRONMENTAL MANAGEMENT DURING OPERATION PHASE To mitigate the problems related to health, safety and environment, an appropriately designed Environmental Management Plan is suggested. The EMP is designed covering all applicable standards or norms prescribed for regulatory and safety viewpoint, however, management will take due course to review the EMP in line with the prevailing norms in totality from time to time.

Ltd. - Ahmedabad Chapter-6 Quantitative Risk Assessment 6.1 Introduction The risk assessment studies have been conducted for identification of hazards, to calculate damage distances and to spell out risk mitigation measures. M/s. Rainbow Papers Limited is the existing unit, involved in manufacturing of Manufacturing of Kraft Paper, Duplex paper, Poster paper and News Print paper-14000 TPM and having Captive Power Generation facilities with rated capacity of 15 MW. Now, management is envisaging increasing power generation capacity to 50 MW by adding 35 MW in two phases (20 MW power generation in Phase-1 & 15 MW power generation in Phase-2) to fulfill the present market demands on same process route. The management is engaged in manufacturing activities since last long time and has a wide experience in the similar field. Scope of Study The scope of work is to carry out risk analysis for the proposed expansion of plant covering all the hazards associated with various process operations, handling of hazardous chemicals and associated activities carried out at any facility. The objective of risk analysis is to further direct greater depth of analysis and suggest remedial measures for hazard potential areas. 6.1.1 Study Objective The objective of the risk analysis includes the following: • Identification of hazards • Selection of credible scenarios • Consequences Analysis of selected accidents scenarios • Risk Mitigation Measures REIA Study for Captive Power plant of Rainbow Papers Limited 6-1 San Envirotech Pvt. Ltd. - Ahmedabad 6.1.2 The Study Approach The risk assessment study broadly comprised of the following steps: • System Description • Identification of Hazards • Selection of Credible Accident Scenarios • Consequence Analysis • Risk Mitigation Measures 6.1.3 System Description This step comprised the compilation of the location, design and operational information needed for the risk analysis. 6.1.4 Identification of Hazards Hazards associated with the plant after expansion was identified. Summary of relevant accident cases was reviewed. 6.1.5 Risk Reduction Measures Based on hazard identification and consequence analysis, risk reduction measures were suggested to reduce risk and enhance safety at the plant. 6.2 Probable Hazards & Risk Hazard identification and risk assessment is carried out through careful study of plant process. Following this various scenarios by which an accident can occur are then determined. Concurrent study of both probability and the consequences of an accident are carried out and the final risk assessment is made. Since chemical & fuel posses’ different kind of hazard, both have been separately associated. The chemicals poses more of Occupational Health Hazard, while fuel posses more of safety / accidental hazards. 6.3 Hazardous Identification • Areas where large quantities of chemicals are stored. • Areas where operating temperatures or pressures could be particularly high. REIA Study for Captive Power plant of Rainbow Papers Limited 6-2 San Envirotech Pvt. Ltd. - Ahmedabad • Areas where flammable inventories exist. • Specific operations associated with the high failure probability like tanker loading / unloading operations. • Areas where passive or active safety systems are associated with a generally high failure rate. At the site except coal and paper, no other combustibles will be handled. Coal will be stored in coal stockpiles. In the power plant, type of likely hazards and possible areas where this can occur are as follows: Area of the plant Type of Hazard Coal Stock Yard Fire Coal Crushers Fire Coal Hoppers / bunkers Fire Coal conveying system Fire Chlorine dosing point(s) Toxic release Acid/Alkali tanks Corrosive liquids and fumes release Transformers / cables etc. Fire Other events giving rise to emergencies being natural hazards, war, sabotage etc. 6.4 METHODOLOGY, APPROACH AND DAMAGE CRITERIA FOR RISK ASSESSMENT Consequence analysis is that part of risk analysis, which considers individual failure cases and the damage, caused by each failure case. It is done to predict the outcome of potentially serious hazardous accidents to man and material in and around the plant boundary limits. The advantages of carrying out consequence analysis are given below: • To improve plant layout (for new projects and for expansion of existing one) • To meet statutory requirements REIA Study for Captive Power plant of Rainbow Papers Limited 6-3 San Envirotech Pvt. Ltd. - Ahmedabad • Protection of public in the nearby areas (no residential / inhabited nearby) • Disaster management planning • Training tool The findings of a consequence analysis provide information about hazardous effects resulting from an accident scenario. In addition, Methods for dealing with possible catastrophic events are also provided. 6.4.1 Failure Case Identification and Definition The first stage in any risk assessment study is to identify the potential event that could result in the release of the hazardous material from its normal containment. This is achieved by a systematic review of the facilities together with an effective screening process. Chemical hazards are generally considered to be of three types: 1. Flammable/ explosive 2. Reactive 3. Toxic At the site, combustibles coal is handled. Potential accidents associated with the plant, section of the plant or pipeline can be divided into two categories: 1. There is a possibility of failure associated with each mechanical component of the facility (vessels, pipes, pumps or compressors). There are generic failures and can be caused by such mechanisms as corrosion, vibration or external impact (mechanical or overpressure). A small event (such as a leak) may escalate to a bigger event, by itself causing a larger failure. 2. There is also a likelihood of failures caused by specific operating circumstances. The prime example of this is human error. However, it can also include other accidents due, for example, to runaway reaction or the possibility of ignition of leaking tank gases / vapours by hot work in the vicinity. REIA Study for Captive Power plant of Rainbow Papers Limited 6-4 San Envirotech Pvt. Ltd. - Ahmedabad The first category of accident requires consideration of each component under its normal operating conditions. Both categories may also require consideration of some components under abnormal conditions. Thus, an essential first stage in failure case identification of such a facility is therefore identifying every significant mechanical component in the plant which could fail, together with its operating conditions, contents and inventory. The range of possible releases for a given component covers a wide spectrum, from a pinhole leak up to a catastrophic rupture (of a vessel) or full bore rupture (of a pipe). It is both time-consuming and unnecessary to consider every part of the range; instead, representative failure cases are generated. For a given component these should represent fully both the range of possible releases and their total frequency. In general, the following typical types of failures are considered: For Vessel/storage tank • Rupture (full bore) • Large leaks (20% equivalent to pipe diameter) • Medium and Small leaks (due to corrosion, impact and other such cases). For pipelines • Full bore rupture • Large, Medium and Small leaks Failures of other components are dealt with in a similar manner giving releases which are representative of accidents to that type of component. For each identified failure case, the appropriate data required to define that case is fed into the software. When the appropriate inputs are defined, software calculates the source terms of each release, such as the release rate, release velocity, release phase and drop size. These source term parameters then become inputs to the consequence modelling. REIA Study for Captive Power plant of Rainbow Papers Limited 6-5 San Envirotech Pvt. Ltd. - Ahmedabad 6.5 Maximum Credible Accident Scenarios As a part of risk assessment study, maximum credible accident analysis (MCA) is carried out to determine the maximum loss scenarios. It is an eventuality, which is possible and will have maximum consequential distances for the particular hazardous chemicals under evaluation. The selection of the accident scenarios is based on the engineering and professional judgment, accident descriptions of the past in similar type of plants & the expertise in risk analysis studies. The MCLS gives the worst possible failure scenarios, which takes into account the maximum inventory that can get released at the time of such a failure. The combustible materials handled in the plant are Diesel and coal. All the MCLS identified involve diesel and the most likely hazard is pool fire. It is assumed that the spilled liquid, in the event of nozzle failure or hose rupture, has encountered a source of ignition, resulting in fire. In order to prevent and control such incidences the tanks and unloading bay will be equipped with various fire protection systems. i.e. fire hydrant network, portable fire extinguishers etc. Also, unloading operation will be continuously monitored. 6.5.1 Methodology for Selection of Accident Scenarios In this study, following steps were followed for scenario selection for risk analysis study: • The hazardous materials to be handled at the plant and the associated hazards were identified and assessed. • Operating and storage conditions of handling and storage of hazardous materials were studied. • An assessment was made of what inventories can get released accidentally. REIA Study for Captive Power plant of Rainbow Papers Limited 6-6 San Envirotech Pvt. Ltd. - Ahmedabad • Release rates were calculated considering deferent cases. For further analysis of selected release sources, representative failure modes and failure sizes were identified. 6.6 DISPERSION MODELS Dispersion modeling aims at estimating the distances likely to be affected due to release of certain quantity of toxic or flammable gas within an acceptable concentration limit. Depending upon the properties of the material released and the release conditions, dense gas dispersion, neutral gas dispersion or a buoyant gas release model is used for estimating the affected areas. Both the models describe the behaviour of material subsequent to its release in the predominant downwind direction, at a particular wind speed and at the existing meteorological conditions. It should be noted that the release rate would depend on release conditions (temperature and pressure), the release/failure point, intervention time, the release area and other factors. Pool fires Pool fires are common fire types resulting from fires over pool of liquid. These generally tend to be localized in effect and are of concern mainly in establishing the potential for domino effects and employee equipment, safety etc. zones. can be Issues relating addressed on to the spacing basis of of critical specific consequence analysis for a range of possible pool fires. The effects of a pool fire depend upon factors such as flammability, combustibility, the amount of material released, temperature, humidity, the pool size, flame height, etc. Damage Criteria The material released due to tank or pipeline failure will form a liquid pool. If the pool encounters an ignition source, it would result in a pool fire. Damage effects due to thermal radiation of varying intensity are given below: REIA Study for Captive Power plant of Rainbow Papers Limited 6-7 San Envirotech Pvt. Ltd. - Ahmedabad Damage Due To Incident Radiation Intensity Incident Type of Damage Radiation Intensity (kW/m2) 37.5 Sufficient to cause damage to process equipment unless the equipment is fully thermally fire protected (insulation, fire proofing, sprinkler protection etc.). 25 Minimum energy required to ignite wood at infinitely long exposure (non-piloted) and would damage thermally unprotected tanks, equipment, etc. 12.5 Minimum energy required for piloted ignition of wood, melting plastic tubing, etc. 4.5 Sufficient to cause pain to personnel if unable to reach cover within 20 seconds, blistering of skin (1st degree burns) is likely 1.6 Will cause no discomfort to long exposure. 0.7 Equivalent to solar radiation. Proposed Fire protection system Adequate fire protection system may be provided as per the applicable Indian codes of practice and a reference may as well be made to recommendations of the Tariff Advisory Committee guidelines.

Dust collection system (ESP) b. Dust suppression system (water spray) c. Open-air construction Where dust collection or suppression systems are installed to prevent dust concentration, appropriate electrical and mechanical interlocks should be provided to prevent the operation of coal handling systems REIA Study for Captive Power plant of Rainbow Papers Limited 6-9 San Envirotech Pvt. Ltd. - Ahmedabad prior to the starting and sustained operations of the dust control equipment. a. Dust suppression systems usually consist of spray systems using water and/or surfactants to reduce the dust generation of coal handling operations. The sprays are normally applied at or near those locations where the coal is transferred from one conveyor to another. b. Dust collection hoppers should be emptied prior to shutting down dust removal systems to reduce the likelihood of collector fires originating from spontaneous heating in the dust hopper. c. High level detection with annunciator alarms should be provided for the dust hoppers. Handling coal fires When fire occurs, and its location and extent have been determined, the best procedure is to dig out and remove the coal in the heated zone as promptly as possible. Drench the hot coal with water as it is exposed. During a coal fire, carbon monoxide and carbon dioxide are formed. It is recommended that canister/cartridge for CO2 be provided to fire fighting personnel. Coal handling system a. All conveyors within 6 ft-8 in. (2 m) of a floor or walkway surface must have alternate passageways. b. Elevated conveyors should have access platforms or walkways on one or both sides. Handrails should be 42 in. (1m) high with an intermediate rail, and platforms should have 4 in. (10 cm) toe boards. Flooring should be of chequered plate or other non-slip surface, particularly on sloping walkways. c. Crossovers or underpasses with proper safeguards should be provided for passage over or under all conveyors. Crossing over or under conveyors, except where safe passageways are provided, should be prohibited. Riding on a conveyor should be absolutely forbidden. d. Pull cord should be provided along the conveyor for emergency REIA Study for Captive Power plant of Rainbow Papers Limited 6-10 San Envirotech Pvt. Ltd. - Ahmedabad shutdown. Operating procedures a. The “start” button or switch for a conveyor should be located so that the operator can see as much of the conveyor as possible. If the conveyor passes through a floor or wall, each area should be equipped with starting and stopping devices, and the simultaneous operation of all starting buttons or switches should be required to start the conveyor. These start-stop devices should be marked clearly, and the area about them must be kept free of obstruction so they can be seen and reached easily. Electrical or mechanical interlocking devices (or both types) should be provided which will automatically stop a conveyor, when the feeds (another conveyor, bin, hopper, or chute), has been stopped or is blocked, so that it cannot receive additional loads. b. If two or more conveyors operate in series, controls should be designed so that, if one conveyor is stopped, all conveyors feeding it are stopped also. c. Emergency stop devices should be approximately located along walkways by the conveyor. Alternatively, a good solution is to have a lever-operated emergency stop device at the tail end of the conveyor, with a strong cord or wire strung on each side of the conveyor for its entire length. A pull on the cord or wire will stop the conveyor. d. On conveyors, where there is a possibility of reversing or running away, anti -runaway, a backstop device can be provided on the conveyor track so that the load (or conveyor parts) cannot slide or fall. e. Fire on electrical motors providing motive power to the belts is another probability. The motor may be over-loaded by excessive friction within the motor itself, obstruction in the driven belt, over loading the belt beyond the capacity of the motor etc. If any of these conditions cause overloading of the motor, heating will increase considerably resulting in the breakdown of insulation, REIA Study for Captive Power plant of Rainbow Papers Limited 6-11 San Envirotech Pvt. Ltd. - Ahmedabad melted soldered connections or bearings burning out. To safeguard the motor, it is recommended that overload relay opening circuit to the motor be frequently checked and should be maintained in a good working condition. In addition to the overload protection customarily provided for electric motors, there should be an overload device designed to protect the conveyor and mechanical drive parts. In the event of an overload, the device must shut off the electric power quickly, disconnect the conveyor or drive parts from the motive power, or limit the applied torque. f. The loading and discharge points of a conveyor carrying material in fine or powdered form should be covered with exhaust hoods and should have good general ventilation, to prevent the formation of dust clouds. Dust removal must be carried out periodically. g. Persons working near or on conveyors should wear tight fitting clothing that cannot get caught in moving parts. Safety shoes are recommended. If the conveyor galleries are dusty, goggles and, if necessary, respirators should be worn. h. Such belts should be protected by automatic system of sprinklers or water spray all the way. The belt drive could be interlocked with the sprinkler system to effect a simultaneous shutdown. i. To help earthing of static charges from belt conveyors, tinsel or needle point static collectors can be placed close to the out-running sides of the drive pulleys and idlers which along with the shafting can be grounded through carbon or bronze brushes running on the shaft. j. Wherever the workers have access to the conveyor it should be possible to switch off the installation by means of an emergency pull-cord which follow the total route of the conveyor. The emergency stop device should be so connected that the installation cannot be restarted from another location except the control room. The overhead conveyor belt should have a collecting tray throughout the route or at least at the road crossings to collect dropping. k. Electro magnets should be installed to remove iron pieces that have REIA Study for Captive Power plant of Rainbow Papers Limited 6-12 San Envirotech Pvt. Ltd. - Ahmedabad been carried over along with the coal cargo. Additional Precautions for Coal Conveyors Each conveyor system should be arranged to automatically shut off driving power in the event of belt slowdown of greater than 20 percent or misalignment of belts. In addition, a complete belt interlock shutdown system should be provided so that, if any conveyor stops, the power to all conveyor systems feeding that belt would be shut down automatically. Coal Conveying and Handling Structures Coal conveying and handling structures and supports should be of noncombustible construction. Fire Protection a. Automatic sprinkler or water spray systems should be provided for coal handling structures. Sprinkler systems should be designed for a minimum of 0.25 gpm per sq.ft. (0.17 L/sec-m2). b. If a sprinkler system is used to protect the coal conveyor, particular care must be exercised in locating closed sprinkler heads so that they will be in the path of the heat produced by the fire and still be in a position to provide good coverage of all belt surfaces along the conveyor. c. Actuation of water spray or sprinkler systems should shut down the conveyor belt involved and all conveyor belts feeding the involved belt. d. Dust collectors fans should automatically shut down along with other related equipment upon detection of fire. e. Draft barriers installed at the end and midpoints of enclosed conveyors should be considered in the fire risk evaluation. Draft barrier will reduce the response time of installed automatic sprinkler or detection systems and minimize the chimney effects in the event of fire. f. Static electricity hazards should be minimized by the permanent bonding and grounding of all equipment, including duct work, conveyor drive belts, pulley, idlers, take-up reels, motor drives, REIA Study for Captive Power plant of Rainbow Papers Limited 6-13 San Envirotech Pvt. Ltd. - Ahmedabad dust collection equipment, and vacuum cleaning equipment. Truck unloading of coal a. Arrangement should be made for suppression of dust of coal. Water can be sprayed on the coal rake / truck before unloading.

REIA Study for Captive Power plant of Rainbow Papers Limited 6-17 San Envirotech Pvt. Ltd. - Ahmedabad CHAPTER-7 Onsite Disaster Management Plan 7.1 INTRODUCTION An emergency is said to have arisen when operators in the plant are not able to cope with a potential hazardous situation i.e. loss of control of an incident causes the plant to go beyond its normal operating conditions, thus creating danger. When such an emergency evolves, chain of events which affect the normal working within the factory area and/or which, may cause injuries, loss of life, substantial damage to property and environment both inside and around the factory take place and a DISASTER is said to have occurred. M/s. Rainbow Papers Ltd. is the existing unit involved in manufacturing of Kraft Paper, Duplex paper, poster paper and News Print paper-14000 TPM and having Captive power generation facilities with rated capacity of 15 MW and now proposes to increase Power generation capacity to 50 MW by adding 35 MW in two phases (20 MW power generation in Phase-1 & 15 MW power generation in Phase-2). As described in previous chapter-6, the risk assessment studies have been conducted for identification of hazards, to calculate damage distances and to spell out risk mitigation measures. Despite of our best efforts in the way of managing an emergency situation lies in the prevention of the any risk hazards from the manufacturing process or material handling, things can go wrong. Therefore, it is essential to plan and develop the support system, which will be required in case an emergency arises. REIA Study for Captive Power plant of Rainbow Papers Limited 7-1 San Envirotech Pvt. Ltd. - Ahmedabad 7.2 PROBABLE HAZARDS & RISK From the preliminary risk assessment study presented in Chapter 6 of this report, some of the possible hazards have been identified. 7.3 OBJECTIVES OF THE PLAN Following are the Objectives of the disaster management plan: 1. To define and assess emergencies, including risk and environment impact assessment. 2. To reduce possibilities of accident 3. To safeguard employees, visitors and other people in the vicinity. 4. To minimize damage to property and / or the environment. 5. To inform employees, general public and the authorities about the hazards/risk assessed, safeguard provided, residual risk if any and the role to be played by them in the event of emergency. 6. To be ready for the mutual aid if need rises to help the neighboring unit. Normal jurisdiction of an On-site Emergency Plan is the own premises only, but looking to the time factor in the arriving the external help of off-site plan agency, the jurisdiction must be extended outside to the extent possible incase of emergency occurring outside. 7. To inform authorities and mutual aid centers to come for help. 8. To affect rescue and treatment of casualties to count injured. 9. To identify and list any dead. 10. To inform and help relatives. 11. To secure the safe rehabilitation of affected area and to restore normalcy. 12. To provide authoritative information to the news media. 13. To preserve records, equipment, etc., and to organize investigation into the cause of the emergency and preventive measure to stop its recurrence. REIA Study for Captive Power plant of Rainbow Papers Limited 7-2 San Envirotech Pvt. Ltd. - Ahmedabad 14. To insure safety of the works before personal re-enter and resume work. 15. To work out a plan with all provisions to handle emergencies and to provide for emergency preparedness and the periodical rehearsal of the plan. The structure of the plan may vary depending on number of employees, materials and processes, availability of resources, location of site, size and complexity of work. The plan should not be complicated. Instructions should not overlap or create any confusion. Responsibilities should be clearly assigned and should be workable smoothly. For clear understanding and quick action, the action (Role) by each individual (his emergency duty) should be prepared in a booklet or card size and given to him. 7.4 IDENTIFICATION OF MAJOR HAZARDS The major hazardous field where disaster management plant is required are as under, • Bursting of high-pressure steam pipe, vessels, etc. due to abnormal pressure rise 7.5 • Fire hazard due to ignition of fuel • Inhalation of any hazardous chemical SCOPE OF PLAN • The plan will set into action immediately after a fire or other hazard occurs in and around the plant • Fuel storage facility is situated away from the manufacturing plant and fulfilling all rules and regulations • All the electrical fittings are of explosion proof fitting • All necessary fire-fighting arrangements have been provided near the storage area REIA Study for Captive Power plant of Rainbow Papers Limited 7-3 San Envirotech Pvt.
